"ROOFTOP" indicates that the returned result is a precise geocode for which we have location information accurate down to street address precision.

RANGE_INTERPOLATED" indicates that the returned result reflects an approximation (usually on a road) interpolated between two precise points (such as intersections). Interpolated results are generally returned when rooftop geocodes are unavailable for a street address.

GEOMETRIC_CENTER" indicates that the returned result is the geometric center of a result such as a polyline (for example, a street) or polygon (region).

When I insert a vector of a couple hundred addresses, a non-trivial percentage comes back as NA's. This is presumably because when the API was pinged for those particular addresses, the status came back as something other than "OK". I think this because when those same entries are inputted individually, the coordinates come out neatly. Any thoughts on how to overcome this? One thought would be to "re-ping" the API each time the status is not "OK," but am wondering how to do so most efficiently. Thanks for any thoughts!

For what it's worth, here's a fairly hackish way of overcoming this issue:
